Аннотация:In the work published last year, we reported the existence of isotypic fluorotrifluoroacetate complexes of lanthanides with the general formula Na2[Ln6(µ3-F)8(η2-CF3COO)12], Ln = Nd, Tb and their crystal structure. These compounds were obtained in trifluoroacetic acid from Ln2(CO3)3 in the presence of NaF. In this work the possibility of synthesizing individual fluorotrifluoroacetate complexes of lanthanides has been shown for the first time and their crystal structure has been studied. In contrast to the island structure of heteronuclear ionic complexes chain structure [Lu2(µ2-F)(η2-CF3COO)4(H2O)3](CF3COO) is formed.
